I am not getting what you trying to do ? If you are trying to use
logic:equal tag
then its use is like as follows
<logic:equal name="mode" value="add">
==code part
Here this mode i set from my action class from which i am loading this page
as request.setAttribute("mode", "add");
In my jsp if there are certain things has to be displayed or some other thign i have to do only if the option i am selecting is "add" only
That part i will give in between by above logic:equal tag
For detailed explanation please go through jakarta struts user guide.There they have given the detailed explanation of tag libraries
All the best

Hi Parijat,
If you are getting this error only while reloading the page and not while original display, here is one reason why:
You are using the logic:equal tag to compare a request attribute with another value.
When the page is reloaded the request attribute is not present and hence the error..
Hope this helps,
